jGnash is a free (no strings attached!) personal finance manager with many of the same features as commercially-available software. It was created in order to make tracking your personal finances easy, but also provides the functionality required by advanced users. jGnash is cross-platform: jGnash 2 will run on any operating system that has a working Java 1.6.0 Runtime Environment (e.g., Linux, Mac OS X, and Microsoft Windows), while the older 1.x series of jGnash will run on systems that support a minimum of Java 1.4.0. (For more information on jGnash 1, including why you might need, or choose, to use it rather than jGnash 2, see JGnash_1.x_Lives!_(And Why).)
